Point taken, Rob. Another thing that needs to be considered is "Duo-Wind" vs "Self Winding" on face. If that is a determining factor for transition from one model to the other, then if this is a Duo Wind, it's possible the entire movement/face assy was replaced with the guts of a Thayer. If case is identical and we are not entirely sure when the name change happened, that could seemingly make it more Thayer than Duo Wind? Maybe this one is case of "potato / potahto".
